A 550B MoE frontier-intelligence open model built for long-running agents. It delivers 5x faster inference and lowers the cost of complex agentic tasks by up to 30% versus other open frontier models.Ultra excels at complex tasks like coding and deep research. Long-running agents spend their time planning, using tools, recovering from failures, and deciding what to do next.

Could you build this?
No Training and serving a 550B MoE frontier foundation model requires massive GPU clusters, tens of millions of dollars in compute, and deep expertise in distributed systems and LLM pre-training.
What it would actually take: Requires clusters of thousands of high-end GPUs (e.g., H100s/B200s) orchestrated with Megatron-LM or DeepSpeed, managing pipeline and tensor parallelism across high-speed InfiniBand fabrics. Pre-training and fine-tuning an MoE model at this scale demands proprietary multi-trillion token datasets, specialized routing algorithms, and custom kernel optimization (Triton/CUDA) for high-throughput inference.
